Title: Dna sequencing by parallel oligonucleotide extensions
Inventor: MACEVICZ STEPHEN C
IPC: C12Q1/68
Filed: 1996-04-16
Abstract: Method and compositions are provided for analyzing nucleic acid sequences based on repeated cycles of duplex extension along a single-stranded template.  Preferably, such extension starts from a duplex formed between an initializing oligonucleotide and the template. As illustrated in the figure, the initializing oligonucleotide is extended in an initial extension cycle by ligating an oligonucleotide probe to its end to form an extended duplex. The extended duplex is then repeatedly extended by subsequent cycles of ligation.  During each cycle, the identity of one or more nucleotides in the template is determined by a label on, or associated with, a successfully ligated oligonucleotide probe. The invention provides a method of sequencing nucleic acid which obviates electrophoretic separation of similarly sized DNA  fragments, and which eliminates the difficulties associated with the detection and analysis of spacially overlapping bands of DNA fragments in a gel or like medium. The invention also obviates the need to generate DNA fragments from long single-stranded templates with a DNA polymerase.

Title: Hierarchical biological modelling system and method
Inventor: KORNMAN KENNETH S
IPC: G16B5/00
Filed: 1996-04-12
Abstract: A hierarchical biological modelling system and method provides integrated levels of information synthesized from multiple sources (116, 118, 120, 121, 124, 126). An executable model (114) of a biological system is developed from information and structures based on the multiple sources. The model is balanced to ensure that it matches the information and structures. Once the model is created and balanced it can be used to provide insight into phenomena at the cellular, or subcellular level, as well as phenomena at the patient, organ and system levels. From this information, clinical trials can be emulated, biologic targets for drug development can identified and subcellular phenomena over time can be observed. The model provides an integrated view of a multi-variable biological system.

Title: System and method for cooling which employs charged carbon dioxide snow
Inventor: RHOADES GEORGE D
IPC: F25D3/11
Filed: 1998-04-09
Abstract: A method and system acts to cool matter through the use of a carbon dioxide snow/vapor flow.  The matter is supported in juxtaposition to an outlet for the carbon dioxide snow/vapor and a conductor which exhibits a reference potential state.  To perform the method, a flow of liquid carbon dioxide is subjected to a pressure expansion to create a flow of carbon dioxide snow and vapor. The carbon dioxide snow and vapor then come into contact with a conductive surface and achieves a charge as a result of frictional engagement with the conductive surface.  Thereafter, the carbon dioxide snow/vapor is directed towards the matter to be cooled and the conductor which exhibits a reference potential.  The reference potential state attracts the carbon dioxide snow and aids in contact thereof on the matter being cooled.

The soil displacing means forces soil out of a cylindrical region (74) around the shaft. The cylindrical region is filled with grout (70) which encapsulates and strengthens the shaft. The grout may be fed by gravity from a bath of grout around the shaft. The soil displacement means has a diameter smaller than a diameter of the screw and may be a disk extending in a plane generally perpendicular to the shaft.

Inventor: CARISSE ODILE
IPC: A01N63/30
Filed: 1998-07-07
Abstract: Apple scab, caused by the fungal pathogen Venturia inaequalis, is considered to be the most important single disease of apple worldwide and one of the most costly to control. Currently, the strategy for apple scab control relies on multiple applications of fungicides, often 8 to 12 fungicide sprays each growing season. These sprays represent an appreciable input of costs to growers and additionally, they can have a substantial impact on the environment. A new microbial pest control agent belonging to the genus Microsphaeropsis has been isolated. The application of this agent after harvest inhibits the formation of pseudothecia of V. inaequalis and consequently reduces the amount of primary inoculum the following spring which will result in a reduced spraying schedule.

Abstract: A fiber array module using soldering, and a fabrication method thereof, are provided. This method includes the steps of forming holes into which optical fibers can be inserted, in a silicon wafer or a ceramic substrate at predetermined intervals, forming a metal layer on the walls of the holes and the entire surface of the substrate, to allow the walls of the holes and the entire surface of the substrate to be plated with a solder alloy material, plating the walls of the holes and the entire surface of the substrate with the solder alloy material, inserting metal-coated optical fibers into the holes plated with the solder alloy material, positioning the optical fibers at the centers of the holes using the surface tension of the solder alloy material, by heating the resultant structure, fixing the optical fibers, inserted into the holes of the substrate, to the substrate by pouring epoxy curable by heat or ultraviolet, to fabricate a fiber array module capable of being accurately attached to an optical waveguide device, and polishing the end of the optical fiber module formed of optical fibers protruding through the holes, to give optical luminance. Accordingly, the environmental characteristics and reliability of a device package are improved upon the connection of the optical fibers. Also, the fiber array module is simply manufactured, and the ends of loaded optical fibers are easily polished, thus fabricating a cheap connection module. Furthermore, the optical fibers are accurately arrayed by the self-alignment using the surface tension of the solder material.
